For the Stafford Unsubsidized and GradPlus I know that interest accrues while in school. How does that work? If you take out $12,000 total for one year of unsubsidized loans at 6.8%, does that accrue every month? I.e.: $816/month for a year, making a total of $9792 in interest in 12 months. That doesn't sound right. Is it 6.8% per year?
